SPECIFICATION forming part of Letters Patent No. 779,342, dated January 3, 1905.

Application filed December 31,1903. Serial No. 187,340.

Ton/ll whom it nut/y concern.-

- the following is a full, clear, and exact description.

. The placing in position on the wheels of vehicles of the outer covers and air-tubes of pneumatic tires,and particularly on those having a considerable diameter and size, is very difiicult to effect and requires a relatively great force. The application of the outer cover to the rim is easily effected for about two-thirds of the circumference of the rim; but it is very difficult to cause the remaining third to pass within the edge of the rim,within which the thickened edge or wire is lodged.

The present invention has for its object an arrangement of apparatus enabling this inconvenience to be obviated and the outer cover to be placed in position on the rim of a wheel without trouble and without submitting it to an excessive strain. This apparatus is applicable to facilitate the placing in position on the rim of either a new or an old outer-cover.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a preferred form of my invention. Fig. 2 is a section drawn on the line A A of Fig. 1. Fig. 3 is a perspective view showing the mode of application of the apparatus for placing the outer covers in position. Figs. 4: and.5 are respectively an elevation and a side view, partly in section, of an accessory piece enabling the apparatus to be applied to facilitate the placing in position of the inner tube; and

Fig. 6 is a perspective view showing this latter application of the apparatus.

In the various views like parts are indicated by similar letters of reference.

The apparatus comprises a kind of plate a,

bent over at one of its ends to enable it to be hooked over the edge of the wheel-rim. This plate a is provided along its side edges with slidegrooves Z), within which can slide a bracket 0, terminated at its upper part by a flat surface (Z, preferably inclined, upon which 5 can rest, as will be hereinafter described, the

edge of the outer cover, which it is desired to place within the edge of the wheel-rim. The two jaws of the bracket 0' support a transverse shaft e, on which can turn a kind of pawl f, which has for its object to hold the bracket 0 fixed upon the plate a. For this purpose the said plate is provided with rackteeth g, (which, as shown in the drawings, are formed by cuts and depressions in the plate a, but which can be obtained by casting or otherwise,) and the lower end of the pawl f is pressed to the bottom of the teeth in question by a coiled spring h, hearing at one end against the rear side of the bracket 0 and at the other against the upper end of the pawl f. Two studs 2 70, Fig. 2, one carried by the bracket, the other by the pawl, are employed to hold the coiled spring /1, in position. The parts being thus arranged, it will be readily understood that if a lever Z, shaped so as to be capable of bearing against the rack-teeth g, is introduced below the axle e and an up-. ward movement in the direction of the arrow X be imparted to this lever (see Fig. 2) the bracket 0 will be caused to rise along the plate a by sliding within the side grooves of the latter. Fig. 3 shows how the apparatus thus arranged serves to place the outer cover in position on the rim. To eifect this operation, there are placed around the wheel a certain number of apparatuses arranged as above described, (the drawing represents two near to each other,) and the edge of the outer cover is arranged on the inclined planes (Z of the brackets of the various apparatuses. Itis only necessary with the lever Z to give successively to each bracket a rising motion to cause the edge or wire of the outer cover to pass over the edge of the rim supporting the apparatuses. The introduction of-the thickened edge or wire of the outer cover into the groove of the rim is facilitated by the inclination of the upper faces of the brackets, upon which the outer cover slides as soon as each of the brackets has been brought into a more elevated position than the edge of the plate a. When the outer cover is placed in position, it is only necessary to cause the brackets 0 to descend on the plates (0 to enable the latter to be disengaged from the This descending movement of the wheel.

brackets is readily effected by pressing with the finger on the upper part of the pawlsf and compressing the springs h.

Certain pneumatic tires, especially those of Wheels of automobile carriages, have valves with somewhat long-bodies, so that their introduction into the holes formed for them in the rims is frequently difficult. My apparatus renders this operation easy. WVith this object I mountupon the inclined plane (Z of this apparatus an additional piece, having, for example, the form ofahookm. (SeeFigs. 4 and 5.) This hook is jointed upon a connecting-piece n, engaging with the inclined plane (Z and enabling it to be coupled with the latter. This coupling being effected, the apparatuses are placed on the rim, as above described and as shown at Fig. 6, and the edge of the outer cover is placed on the upper part of the pieces m. Then by causing the brackets to rise to the position represented in the drawing the edge of the outer cover is raised very high, so that the fingers can be readily introduced into the interior of the outer cover to pass the body of the valve 0 through the hole in the rim or to effect any other operation necessary to a pneumatic tire. The operation finished, the brackets are caused to descend, the hooks are withdrawn, and the outer cover is placed in position, as above described.

I would have it understood that the forms, dimensions, and arrangements of detail of the V apparatus may be varied without departing tires on safety-bicycles and the like the apparatus might be reduced in dimensions and simplified. For example, the lever might form part of the apparatus instead of being separated therefrom.

I claim 1. An arrangement of apparatus for applying outside rubber tires on wheel-rims, this apparatus comprising a bracket, a plate which can be fixed to the wheel by any suitable means and upon which can slide upward or downward at will said bracket carrying the edge of the cover for the purpose of bringing the same within the edge of the wheel-rim, and an additional piece for holding the cover in a raised position.

2. A device for placing outer covers of tires upon wheel-rims, comprising means for engaging the rim of a wheel, a slide mounted upon said means and movable relatively thereto, said slide being provided with a portion for engaging a tire cover, and means for moving said slide relatively to said first-named means.

3. A device for placing tire-covers upon wheels, consisting of a member provided with a hook portion for engaging the rim of the wheel and with a portion for resting against one of the spokes thereof, said member being provided with rack-teeth, and a slide mounted upon said member and provided with a pawl for engaging said rack-teeth, said slide being 'further provided with a portion for engaging the tire-cover.

4:. A device for placing tire-covers upon wheels, comprising a member provided with a portion for engaging the edge of the rim of the wheel, a slide mounted upon said member and movable relatively thereto, and mechanism for retaining said slide upon said member so as to prevent backward movement of said slide relatively to said member.

5. In adevice for placing tires upon wheels, the combination of a member provided with a hook portion and with a toothed rack, a slide mounted upon said member and provided with a pawl engaging said toothed rack, a roller mounted upon said slide, and means for engaging said roller and said rack for the purpose of moving said slide relatively to said member.

6. The combination of a member to be secured upon the framework of a wheel, a movable member mounted thereon, and free to move relatively thereto, and mechanism engaging said last-mentioned member and provided with a portion for engaging the edge of the cover of a tire.

7 The combination of a member provided with a hook portion for engaging the rim of a wheel, and also provided with a portion for resting against one of the spokes of the wheel, a slide mounted upon said member and movable relatively thereto, a member provided with a portion for engaging cover of a tire, means for connecting said last mentioned member with said slide, and means for actuating said slide relatively to said member provided with said hook portion.

The foregoing specification of my apparatus for facilitating the placing in position of the outer covers and air-tubes of pneumatic tires signed by me this 7th day of December, 1903.
